Don't know whats wrong, someone help me out.

Hello,

For the past 3 months I have been experiencing a very strange feeling. It all started 6 days before new years when I was taking a shower after work, all of the sudden I believe I had a Panic Attack, I had a strange feeling of being incredibly scared, light headed, like I was about to hit the floor. I got out and laid down for about 5 minutes and then everything seemed to get great, so I went out that night. The next morning I couldnt believe how horribly I felt, heart pounding being absolutely frightened of death, and Im 19 and excersice 3 times a week and in good shape, so I figured it couldn't be my heart. the next 4 weeks were the worst in my life. The worst part was this incredibly scarry feeling of being detached from my body like things were unreal, my vision seemed foggy and fuzzy like I had just woken up. I couldn't focus on anything. 2 months into I just couldn't take it, for the first time in my life I actually felt like I wanted to die to get away from this, I was scared of even drinking, something I usually liked to do, because my everyday life seemed like I was constantly buzzed, a perfect way of describing how I feel is that buzz after taking a smoke of a ciggerete. I live in alaska and found out about SAD. I thought maybe I had that, but I just dont know what is going on with me, It has gotten better but I think I might have gotten Labyrnithitis or something. I got a blood test done and everything came back perfect. I found myself crying about never feeling good feeling like one shower changged my life and ruined it. I just dont know where to get help from and from what sources. If someone could please tell me anything about this I would appreciate it. Thank you..
